+ * <p>Wildcards are allowed only instead of the entire type or subtype with a tree prefix.

+ * it will not match image/jpeg. Suffixes and parameters are not supported, and they are treated
+ * as part of the subtype during matching. Neither type nor subtype can be empty.
+ *
+ * <p><em>Note: MIME type matching in the Android framework is case-sensitive, unlike the formal
+ * RFC definitions. As a result, you should always write these elements with lower case letters,
+ * or use {@link android.content.Intent#normalizeMimeType} to ensure that they are converted to
+ * lower case.</em>
+ *
+ * <p>MIME types can be null or ill-formatted. In such case they won't match anything.
+ *
+ * <p>MIME type filters must be correctly formatted, or an exception will be thrown.

-# Dependency platform-robolectric-android-all-stubs below contains a bunch of Android classes as
-# stubs that throw RuntimeExceptions when we use them. The goal is to include hidden APIs that
-# weren't included in Robolectric's Android jar files. However, we are testing the framework itself
-# here, so if we write stuff that is being used in the tests and exist in
-# platform-robolectric-android-all-stubs, the class loader is going to pick up the latter, and thus
-# we are going to test what we don't want. To solve this:
-#
-#   1. If the class being used should be visible to bundled apps:
-#      => Bypass the stubs target by including them in LOCAL_SRC_FILES and LOCAL_AIDL_INCLUDES
-#         (if aidl).
-#
-#   2. If it's not visible:
-#      => Remove the class from the stubs jar (common/robolectric/android-all/android-all-stubs.jar)
-#         and add the class path to
-#         common/robolectric/android-all/android-all-stubs_removed_classes.txt.

-/**
- * HACK
- * Robolectric loads up Android environment from prebuilt android jars before running a method.
- * These jars are versioned according to the SDK level configured for the method (or class). The
- * jars represent a snapshot of the Android APIs in that SDK level. For Robolectric tests that are
- * testing Android components themselves we don't want certain classes (usually the
- * class-under-test) to be loaded from the prebuilt jar, we want it instead to be loaded from the
- * dependencies of our test target, i.e. the system class loader. That way we can write tests
- * against the actual classes that are in the tree, not a past version of them. Ideally we would
- * have a locally built jar referenced by Robolectric, but until that happens one can use this
- * class.
- * This class reads the {@link SystemLoaderClasses} or {@link SystemLoaderPackages} annotations on
- * test classes, for classes that match the annotations it will bypass the android jar and load it
- * from the system class loader. Allowing the test to test the actual class in the tree.
- *
- * Implementation note: One could think about overriding
- * {@link RobolectricTestRunner#createClassLoaderConfig(FrameworkMethod)} method and putting the
- * classes in the annotation in the {@link InstrumentationConfiguration} list of classes not to
- * acquire. Unfortunately, this will not work because we will not be instrumenting the class.
- * Instead, we have to load the class bytes from the system class loader but still instrument it, we
- * do this by overriding {@link SandboxClassLoader#getByteCode(String)} and loading the class bytes
- * from the system class loader if it in the {@link SystemLoaderClasses} annotation. This way the
- * {@link SandboxClassLoader} still instruments the class, but it's not loaded from the android jar.
- * Finally, we inject the custom class loader in place of the default one.
- *
- * TODO: Remove this when we are using locally built android jars in the method's environment.
